TOWEL-SEPARATING MECHANISM FOR LAUNDERTNG MACHINES.

Application filed May 5, 1924.

To @ZZ 'whom it may concern.'

Be it known that we, VILLIAM W. TRiNKs and BENJAMIN W7. TUCKER, citizens of the United States, and residents, respectively, of

' Bridgeport, in the county of Fairfield and State of Connecticut, and South Orange, in 'the county of Essex and State of New J ersey, have invented a new and useful Towel- Separating Mechanism for Laundering Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper` tains to make and use the same.

In one type of towel cabinets now in quite general use the towel is rolled on a mandrel from which it is dra-wn in successivo lengths as required for use, and, as the successive lengths are drawn from the cabinet,

the preceding soiled lengths are automatically wound about a second mandrel in the cabinet. Thus the towel is in roll form both when placed in the cabinet clean and when removed therefrom soiled.

A machine for laundering such rolled towels is disclosed in a co-pending application, Serial No. 516,806, filed November 21, 2021, the saine comprising a washing means, a feeding means for unwinding the rolled towel and carrying the same through said washing means, and winding means for receiving the laundered towel from the feeding means and automatically rfc-winding the saine into roll form ready for use again in the cabinet.

Because of the towels being in roll forni when talien from the cabinet and during the subsequent manual handling of the same, it is obvious that damaged or torn towels are not readily detected. It has therefore been the main object of our present invention to tion of the torn towel deflector and its latching mechanism which is located at the rea;l

provide a simple and eflicient means for separating torn from untorn towels. This we Ar-.ccoinplish by equipping the laundering machine of our aforesaid application with means which is operative, through engagement with the towels when being drawn through the machine in a flat or unrolled condition, to detect torn towels and sulose` quently separate the same after being rolled up from the untorn ones.

Our invention in one form thereof com- Seria'l No. .71,1131.

prises a deflector located at the rear of the winding mechanism for movement to and` from a position across the normal path of and rotatably mounted detector members lon cated in advance of the winding mechanism in yielding engagement with the uiirolled towels whereby they will be caught in any opening or tear in a passing towel and rotated by the latter, which rotation of the detectors will act through suitable connections to release the latch from the deflectoi and effect a movement of the latter to operative position to dciect the torn towel from its normal path of discharge, following which the deflector will be automatically returned to its normal inoperative position so as not to interfere with the normal passage of the untorii towels.

Referring now to the accompanying drawings,

Figure l is a side elevation of that pari of thc machine of our aforesaid application which is provided with the winding mechanism, the same also being here equipped with the torn 'towel detecting and separating mechanism of the present invention.

Fig. 2 is a top plan of part of the machine shown in Fig. l with the mandrel supporting and feeding devices of the winding mechanism removed.

Fig. 3 is a side elevation of that part of the machine shown in Fig. 2 with one of the side frames partly broken away.

Fig. t is an enlarged detail in side elevation of the-torn towel detecting mechanism at the front end of the winding mechanism,

and

Similar reference charactersindicate like parts in the several figures of the drawings.

In the machine of our aforesaid application, the towels are adapted to be fed through the laundering machine proper by a pair of endless carrier belts which loosely connect with the opposite ends of a bar that is vpassed through a loop in the leading end Iii of the towels. After being fed beyond the laundering machine proper, the bar in the leading end of the towels is taken from the main carrier belts by a second pair of feed belts which latter delivers said bar with the connected towel to a winding mechanism which winds up the laundered towels and discharges them from the rear end o f the machine in roll form.

The main carrier belts referred Lto are .in

lthe form of sprocket chains mounted on suitably arranged pairs of guiding and operating sprocket wheels, such belts in the present case being diagrammatically indicated by the broken lines 53 and .certain pairs of the sprocket wheels lbeingpiifidicated at 145, 1416, 147, 1418 and 149, the wheels 147 being mounted on a shaft 150 which is driven from a main drive shaft 10 at the side of the machine through bevel lgearing 151. y

The second pair of feed belts, Atermed the releasing Vbelts and diagrammatically shown by the broken lines 220, are yalso in the form of endless sprocket chains which are mounted on pairs of sprocket wheels 221, 222, and 223,'the first two ipair being guide wheels'and the last pair, those indicated at 223, being drive wheels and mounted on an intermittently operated clutch-controlled shaft `176. rfhese feed belts 220, which are operated to move at a greater speed than that of the main carrier belts, 'are provided with projections 224 which are moved 'in -paths lto engage the ends of the ltowel bar 55 adjacent the rear end of the upper run of the main feed belts 53 and lrelease said bar from the latter and deliver it to the towel winding mechanism.

The towel winding mechanism Vhere shown is the same as that fully illustrated and described in our aforesaid application, `but as Lthe same acts yto some extent in cooperation with the torn towel Vdetecting and separating mechanism of the 'instant invention, we will briefly describe the same here. This winding mechanism comprises a plurality of endless belts 160 which are Ymounted on a series of sets of pulleys, such as indicated .at 161, 162, 163, 164 and 165, certain of which are adjustable relatively to the vothers to permit of the upper run of vbelt being driven from the pulleys 162 which are -itto .drop 4onto the upper run of belts, which at such time is in the straight dotted line position a of Fig. 1, after which, by a continued downward movement against the tube,l 4the plunger depresses both said tube andthe 'upper run'of belts'downwardly between the adjacent sets of pulleys 162 and 163. '/Vhen ,the tube is ythus pressed downward Yby the plunger' ,o against the upper run of 'belts to `form a loop therein, the pulleys 163 are at the same time moved forward towards the adjacent pulleys 162, as from the dotted line position b shown in '1 to the-full line position shown, in order to cause the belts to closely embrace the tube and thereby more effectively assure the winding of the towel thereon when its leading end is moved into said loop of the winding'be'lts by the ,carrier belts 220. As V the winding operation proceeds following the entry of the leading end of the towel into the winding loop and about the tube therein, the diameter of the rolled towel of course .Gradually incieases, as shown in Fig. 1, therenymaking it necessary that the size ofthe winding loop should correspondingly increase. To'provide for such increase in the size of the 'winding loop by automatically acting means, Vthe shaft carrying the pulleys 165 is mounted ai lever arms 1T() which are pivoted to the frame 1*!'1 andvpro- Vvided with attached weights l? 2. Such movr162 toclose ythe mouth of the winding loop and theplunger-remains in -itslowered posi- -tion opposite Vsaid mouth of the loop; in

this-way serving lto hold the towel in the winding loop of the belts duringfthe winding operation. After the winding operation has beenv completed the pulleys 163 are automatica-llythrown back and the plunger raised, to release the-rolled up towel t and permit its discharge from the machine. Such. operations of the pulleys 163 and plunger p are automatically controlled from the intermittently operated clutch controlled shaft l176 through suitable connections,

which it is not necessary to here describe for the proper' understanding of the present invention, such connections and their operation being shown and described in detail in our aforesaid application to which reference may be had.

When the rolled up towels t are discharged from the winding mechanism, they will, in following their normal path of discharge, drop from the winding belts into a transversely arranged trough 2 through which passes a conveyor 3 for delivering the towels to a desired location.

In accordance with our present invention, as hereinbefore referred to, we locate a detecting` mechanism in advance of the winding mechanism which is operated by the passing of torn towels to cause a deflector at the rear of the winding mechanism to engage such torn towels and separate the same from the untorn ones by deflecting them from their normall path, i. e. in the case here shown the path leading to the trough 2.

The deflector is here shown in the form 3 of a tilting Aplatform comprising a series of slats 5 fixed to a shaft 6 supported at its ends in journal blocks 7 on the side frames 140 in position whereby the platform may be tilted to and from a position with one end projecting into the path of the rolled towels as they are discharged from the winding belts, as shown by the dotted line position in Fig. l, in which position it will receive a rolled towel thereon and deflect it from its normal path leading to the trough 2. When in such towel intercepting position, the platform is held in an inclined position sloping downwardly towards its rear end by the engagement of an arm 8 on the f shaft 6 with a stationary stop pin 9 on the frame, whereby the towel received thereon will be caused to gravitate to the rear end of the platform and be discharged therefrom at a point distant from the normal point of discharge into the trough 2, as will be clear by reference to Fig. l.

The deflector platform is normally held in the inoperative position shown by full lines in Figs. l, 2 and 3, by means of a latch ll pivotaliy supported on the frame at l2 engaging with a tooth 13 on a segment lli fixed to the shaft 6, as shown in Fig. 3. ln this position of the deflector the normal path of the towels from the winding mechanism to the trough 2 is left open and unobstructed. Upon the release ofthe deflector by the disengagement of the latch from the segment tooth 13, it is automatically thrown into operative towel deflecting position by a spring l5 which connects at one end with a pin 16 on the segment la and at its opposite end with a fiXed pin l? on the frame. Such release of the deflector by the latch is automatically effected only through the detecting means at the front of the winding mechanism when this is brought into opera.- tion by the passing of torn towels as will now be described.

The detecting means in a preferred embodiment of the invention comprises a plurality of plural-armed members 2O rotatably mounted for independent rotation on a sha-ft 2l which is supported adjacent its opposite ends in the outer ends of two arms 22-22 fixed to a rock-shaft 23, which latter is mounted in suitable journal blocks on the opposite side frames of the machine. The members 2O are adapted to be normally held with one arm thereof in yielding engagement with the passing towels, as shown in Fig. 3, whereby one or more of the same will be caught in any opening or tear that might occur in a passing towel, and the member being so caught, will be partially rotated by the engaging towel as shown in Fig. 4;; the table 24 over which the towels pass beneath the members being longitudinally slotted to permit of the rotation of the ends of the arms of said members in a path beneath the top of the table as shown. Such rotation of any one of the detector members 20, as effected by one of its arms being caught in an opening of a passing towel, acts to bring another of its arms into engagement with the oppositely located arm 25 on a rock-shaft 26 journalled in blocks 27-27 on the opposite side frames of the machine (Fig. 2) and effect a rocking of said shaft, which action of the latter is operative through suitable connections to release the latch l1 from latching engagement with the segment 14 whereby the defiector may be thrown into operative position under the action of the spring l5 to intercept such torn towel as it is discharged from the winding mechanism and deflect it from its normal path so as to separate the same from the untorn towels. The said connections between the rock-shaft 26 and latch ll comprise a short lever arm 30 on the rock-shaft connecting through a long link 3l with a second lever arm 32 fixed to the latch.

lWhen a detector member has been rotated by an engaging towel sufiiciently far to release its arm from engagement with the cooperating rocher-arm 25, the latter and associated roch-shaft will return to their normal position under the action of a spring 33 connecting at one end with a fined pin 34 on the frame and at its opposite end with a pin 35 on the latch arm When these parts are thus moved under the action of the spring 33, the latch il is also thereby moved into yielding contact with the lower edge of the segment lli whereby it will be caused to snap into latching engagement with the segment tooth 13 upon the movement of theI deflector plat form to its normal inoperative position, as shown in Fig. 3. rlhe deiector is preferably limitedL uponf reaching the latter position by the engagement of its arm 8 with a second' stop pin 36 on the Jtrame.

As hereinbetore referredl to, the detector members` 20 are adapted to be normally held with one arm thereof in yielding contact with the passing towels, as shown in Fig. 3; This is etiected by securing a cam disk Ll0 to each detector member andl mounting on the shaft 23v a plurali-ty ot ,inde` pendently movable spring-pressed arms il-.1 carrying rollers Llf2 at their tree ends in engagement with the cam dislrs e0. These latter, as here shown, have three peripheral notches or Vdepressions corresponding in number with the detector arms and which notches are so positioned relative to the latter that when entered by the roller et a co-acting spring arm, the end of a corresponding detector arm will be held in pcsi'tion forv engagement with a towel. Upon the partial rotation of a' detector member as eected by the engagement therewith ot a tor-n towel, thev co-actingl spring arm will'ryiel'd to permit ot snch rotation by riding up on the adjacent high ot the cam, as shown' in 4T. Thereafter, when the detector has been rotated sur'iiciently far by the engaging towel to move the high part ci' the cam past the engaging spring arm, the roller on the latter will be pressed `down into the succeeding notch of the cam and so automatically bring the succeeding arm et the detector into'engagement with the towel. This operation is repeated upon each aartial rotation ot the detector by an engaging torn towel. The yielding action ot the arms il may be provided for in any suitable way. In'the present case a series of coiled spring-s 43 are; located on the shaft 23, each connected at one end with a collar te iixed to the shaft and at its opposite end connected to anv adjacent arm el, whereby eacn arm will be capable ot independent spring action.

lt will of course be obvious that any desired number of detector members .-nay be employed, this depending primarily on the width of the towels to be acted on. A number of them are desirable in any event so as to detect an opening or tear at any point in the width of the towels. lt a tear is small, it may catch only one detector, but this will act to bring the deflecter into operation in the same manner and quite as eiectively as though the tear was large enough Vto catch and operate several oil" the detectors.

The detector members in their normal op erative position for pressing engagement with the towels are in the path ot the bar 55' in the leading end of the towels, and, 'if engaged by said bar, would bring' the detlector into operation. To avoid this, the shaft 23, which carries at the tree ends of its arms 22e-22 theshafftl and supportedz detector members, isrocuked in timed relation with the movement ot the towel feed belts 220v' to raisethe detector members above the path et the` towel' bar upon the approach of the latter, and, uponv the passage of said bar, lower themembers into engagement with the towel: rlfhe means for etiecting such movement et the detector members` 'th-rough the rockeshatt 23, comprises an arm 50 fixed tothe rea-r end of the' shaft, bar 51 connecting' .at one4 end with said arm and ,atits opposite or lower end being: longitudinally slotted tor sliding engagement with the shaft 127.6, and a grooved cam 52 on the sha-tt 1,76' engaging Arol-ler o6 on the bar 5l. (Fig. e), said cam being termedl to impart the described raising and lowering movements tothedetector members through the intermediate connections. y

The operation' ot VVthe machine, briefly stated, is as follows: When the bar` in the lead'ng end ot a towel is brought by the main carrier belts to the releasing belts 220, the latter, through the projections 224 thereon, engage said bar andv carries the same with the connected ytowel over the table 24 to the winding'mechanism. During such movement of the towel bar, the .detector members are raised above the path ot the latter to permit of its passage therebeneath and then lowered onto the towel. lt such towel is undamaged, that is, if it has no tears or .openings therein, it passes to the winding mechanismfwithout effecting any operation et the detecting and separat .-0

mechanism, and, upon its discharge i l' l C rom the winding mechanism, vdrops into the trough 2 to be carried to the desire-d delivery point bythe conveyor 3. lt howeyer a torn towel comes 'through and is taken by the ieed beltst 220, the tear or tears the-rein w'l'l catch .one or more ot the detector members 2O and cause a partial rotation ot the same, thereby bringing one cit their arms into'engagement with onelot the arms on the rock sha-tt 26' to'rocl' thelatter and" thereby effect a release of the latch l1 from the segment lll of the detector platform, whereuponv the latter will be tilted under the action ot the spring l5 from .the inoperative position shown by full lines in Figs. l and 3, to its operative deflecting position shown by dotted lines in Fig. lyin which latter position it will intercept and' receive thereon said torn towelA as it energes in roll form 'from the winding: mechanism. When the towel is thus received on the defiecting platform, it rolls to the rear end ot the latter and thereby acts lto reset the same in its normal inoperative position by bringing the locking tooth 13 on #the'seginent 14 into locking engagement with the latch 1l, as `shown by dotted lines in Fig. 3. The mechanism for detecting and separating torn towels is thus automatically operated and reset in normal position by each torn towel as the latter passes through the machine. l/Vhen not operated by the passage through the machine of torn towels such mechanism remans inoperative.
